who believes in kismet

sounds fair to me......im confused though....so say we gets lots of rishtas where we have free will to say yes to any of them...but whoever we say yes to,is kismet,,and god knows this already? see this makes sense..but

say god gives you the perfect partner...( u think) and u both love each other, but then for silly/petty/stupid/game playing/juvenile behaviour it all goes pear shaped and you never speak to them again...due to ur own idiocy, does that mean this was also planned out...that this would happen....if your meant to meet me one day and we plan to meet, but that meeting never happens, does that mean its ourown free will we never met, or god knew we wouldnt meet?
